Let's run some troubleshooting steps to identify why you're unable to relink your bank accounts, suzymiller.
First, let's connect the bank account on a private window. It is the best place to identify any browser-related issues. You can use these keyboard shortcuts to open one:
Google Chrome: Ctrl + Shift + N
Mozilla Firefox: Ctrl + Shift + P
Microsoft Edge: Ctrl + Shift + P
Safari: Command + Shift + N
Second, if it works, we can go back to your regular browser and clear its cache. A piled cache can also be the reason for some unexpected issues on the opened pages.
Then, we also have the option to use a different browser like Google Chrome, Mozilla Firefox, Safari, or Microsoft Edge.
